🔌 Function

  

The stator generates AC charging output under the flywheel. The rectifier / regulator converts this output into DC voltage for battery charging and electrical-system operation.

  

Common signs of failure:

  

• Battery not charging

• Charging voltage low or unstable

• EFI electrical faults caused by low system voltage

• Hard starting from poor battery recovery

• Electrical accessories draining the battery while running

• Burnt winding smell or discoloured coil windings

• Damaged connector or broken stator leads

• AC output below specification during testing

  

📦 Condition

  

• Genuine used part

• Removed from running engine where applicable

• In good working condition unless otherwise stated
